@Phally well we could go either way. It is my opinion that we need both. If i had to choose just one it would be the showcasing aspect.
@jippi that is exatcly how I wanted to incorporate the builditwith.me aspect of it: a two phase plan of attack. I figured as enthusiasts and developers see our ( the cake community's ) work, the next step would be to open a channel of communication between the developers of the app/plugin and those looking at the work. Since developers in the community would be spending time looking at how certain apps/plugins work, I figured we could take that opportunity to let them know that there are projects that they could be part of; existing or just project ideas. The point is to make it is super simple to help people become more involved because they would search for stuff that interests them from the perspective of "I would like to work on that" rather than "I need this feature/plugin". I am inclined to believe that the former would motivate more involvement by most in the community than the latter. Evidence of this has been seen in IRC. Also, and this is a pet peeve of mine, seeing projects on GitHub with a high number of forking and little to no PRs is another indicator that people in the community are using the apps/plugins but perhaps need to be educated or motivated on how/why it is important to contribute.  Hopefully it would start a trend that would move developers from solely being consumers to becoming contributors ( which I would love to see more of ).
